Strawberry plant named ‘DrisStrawThirtyFive’

ABSTRACT

A new and distinct variety of strawberry plant named ‘DrisStrawThirtyFive’ particularly characterized by high yield, long shelf life, and medium red berries with sweet flavor, is disclosed.

Genus and species: Fragaria×ananassa.

Variety denomination: ‘DrisStrawThirtyFive’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry varietydesignated ‘DrisStrawThirtyFive’ and botanically known asFragaria×ananassa. This new strawberry variety was discovered in Kent,United Kingdom in May 2008 and originated from a cross between theproprietary female parent ‘KGEM 0148’ (unpatented) and the proprietarymale parent ‘KGEM 0175’ (unpatented). A single plant was selected forasexual propagation via tissue culture and vegetative cuttings in Kent,United Kingdom.

‘DrisStrawThirtyFive’ underwent further testing in Kent, United Kingdomfor five years (2008-2012). The present invention has been found toretain its distinctive characteristics through successive asexualpropagations via stolons and tissue culture.

Plant Breeder's Rights for this variety have not been applied for.‘DrisStrawThirtyFive’ has not been made publicly available or sold morethan one year prior to the filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new cultivar when grown under normalhorticultural practices in Kent, United Kingdom.

-   -   1. High yield;    -   2. Long shelf life; and    -   3. Medium red berries with sweet flavor.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

When ‘DrisStrawThirtyFive’ is compared to the female parent plant ‘KGEM0148’ (unpatented), ‘DrisStrawThirtyFive’ has higher yields, bettershelf life, and better flavor than ‘KGEM 0148’.

When ‘DrisStrawThirtyFive’ is compared to the male parent plant ‘KGEM0175’ (unpatented), ‘DrisStrawThirtyFive’ has higher yields, bettershelf life, better flavor, and better resistance to Verticillium wiltthan ‘KGEM 0175’.

When ‘DrisStrawThirtyFive’ is compared to the commercial variety‘Sonata’ (U.S. Plant Pat. No. 18,000), ‘DrisStrawThirtyFive’ has leaveswith an acute base, freely spaced, orbicular shaped petals, and a mediumflowering time, whereas ‘Sonata’ has leaves with an obtuse to roundedbase, overlapping, broadly ovate shaped petals and an early floweringtime. Additionally, ‘DrisStrawThirtyFive’ has medium red berries with asmall hollow center, whereas ‘Sonata’ has light red berries with anabsent or weakly expressed hollow center.

We claim:
 1. A new and distinct variety of strawberry plant named‘DrisStrawThirtyFive’ as described and shown herein.
